Anal Fin Pigmentation In Brachyrhaphis Fishes Is Not Used For Sexual Mimicry, Kandace Mary Hugentobler
Anal Fin Pigmentation In Brachyrhaphis Fishes Is Not Used For Sexual Mimicry, Kandace Mary Hugentobler
Theses and Dissertations
Pigmentation patterns can be used as a communication signal in a variety of taxa, and can convey information relative to sexual selection, dominance, and species identification. Pigmentation is also sometimes used in mimicry to deceive the signal receiver into thinking the signaler is something other than itself. Mimicry can occur in several contexts, including sexual interactions, where one sex mimics another. There are relatively few examples of species with females that mimic males. Proposed hypotheses to explain female mimicry of males are that mimicry is used to reduce male harassment or that mimicry is used to display dominance over other …
The Tettigoniidae (Orthoptera: Ensifera): Phylogeny, Origins, And Leaf-Like Crypsis, Joseph D. Mugleston
The Tettigoniidae (Orthoptera: Ensifera): Phylogeny, Origins, And Leaf-Like Crypsis, Joseph D. Mugleston
Theses and Dissertations
Tettigoniidae (katydids) has more than 7200 species and is the largest family within the insect order Orthoptera. Their unique biology including leaf-like crypsis, acoustic signaling, and courtship rituals garners much of their academic attention. However, the taxonomy of katydids is chaotic and previous to these studies, little work had been done to decipher the phylogenetic relationships within this family. Without a robust phylogenetic framework, questions regarding the evolution of katydid disguises including the leaf-like crypsis cannot be addressed. This dissertation contains three chapters. Chapter 1 provides the first phylogenetic hypothesis focusing on Tettigoniidae. In this chapter we show a character …
Molecular Studies Of South American Teiid Lizards (Teiidae: Squamata) From Deep Time To Shallow Divergences, Derek B. Tucker
Molecular Studies Of South American Teiid Lizards (Teiidae: Squamata) From Deep Time To Shallow Divergences, Derek B. Tucker
Theses and Dissertations
I focus on phylogenetic relationships of teiid lizards beginning with generic and species relationship within the family, followed by a detailed biogeographical examination of the Caribbean genus Pholidoscelis, and end by studying species boundaries and phylogeographic patterns of the widespread Giant Ameiva Ameiva ameiva. Genomic data (488,656 bp of aligned nuclear DNA) recovered a well-supported phylogeny for Teiidae, showing monophyly for 18 genera including those recently described using morphology and smaller molecular datasets. All three methods of phylogenetic estimation (two species tree, one concatenation) recovered identical topologies except for some relationships within the subfamily Tupinambinae (i.e. position of …
Phylogenetic Relationships Of Cottids (Pisces: Cottidae) In Upper Snake River Basin Of Western North America, Sun Yeong Oh
Phylogenetic Relationships Of Cottids (Pisces: Cottidae) In Upper Snake River Basin Of Western North America, Sun Yeong Oh
Theses and Dissertations
Freshwater sculpins (Cottus) are common throughout temperate regions of the Northern Hemisphere. Their broad distribution in the Western North America makes them a good model for understanding phylogeographic relationships among western fishes. Within much of the interior west three lineages, C. bairdii, C. confusus, and the C. beldingii complex, are most prevalent. The distribution of these three overlap in the Snake River Basin. All occur below Shoshone Falls on the Snake River. However, only two currently reside in the Upper Snake River above the falls. An exception are the Lost River streams of central Idaho. While …
Accepting Evolution And Believing In God: How Religious Persons Perceive The Theory Of Evolution, Katherine F. Manwaring
Accepting Evolution And Believing In God: How Religious Persons Perceive The Theory Of Evolution, Katherine F. Manwaring
Theses and Dissertations
Students frequently hold an incorrect view of evolution. There are several potential barriers that prevent students from engaging evolutionary theory including lack of knowledge, limited scientific reasoning ability, and religiosity. Our research provides tools for overcoming barriers related to religiosity and diagnoses the barriers preventing students from fully engaging in learning the theory of evolution. This was a two-part study. The first part of our study addressed two hypothesized barriers to learning evolutionary theory among members of The Church of Jesus Christ of Latter-day Saints (LDS or Mormon): (1) religious views stemming from incorrect understanding of the Church's neutral stance …
